DescriptionAn electronic management system supervises and governs all engine parameters. It optimises performance and fuel consumption by responding in real time to different service conditions.The system is managed by a single control unit that controls the twin spark ignition (static and lost spark), and the injection (phased).The system uses signals received from numerous sensors to control actuators. It is connected to the following systems:fuel supply;air supply system;accelerator pedal;engine cooling;exhaust with catalytic converter;fuel vapour recirculation.On this version, the engine is fitted with a throttle body controlled electronically by the control unit. The opening of the throttle is calculated in accordance with a specific logic within the engine management control unit; This dispenses with the need for a mechanical connection between the accelerator pedal and the throttle body. For more details, 3308466see DESCRIPTION AND OPERATION:1056PETROL INJECTION SYSTEMSupply lines to the control unit and the various system components (sensors and actuators) are protected by a special maxifuse and another protects the steering wheel fuses, located with the relays in a service tank (behind the engine bulkhead).
Functional description The engine control unit M10 monitors and controls the entire electronic ignition and injection system. The control unit is supplied directly by the battery via a line protected by maxifuse CENTR of B5 at pin 4 of connector B of M10 via the line protected by fuse F20 of junction unit B1.The main fuel injection relay J10 controls the entire system: it is supplied directly by the battery via the line of maxifuse B80; it is energized by an ignition-dependent signal (INT/A) by the line protected by fuse F16 of junction unit B1; the main relay J10 thuse sends a supply:to pin 2 of connector A of control unit M10 ;to injectors N70 ;to the coils A30 ;to timing sensor K47 , via a line protected by fuse B40.to air flow meter K41 , via a line protected by fuse B40 ;to fuel vapour recovery solenoid L10 , via a line protected by fuse B40 ;to the Lambda sensor heater K40 , via the line protected by fuse B40 ; The ignition-operated power supply (INT/A) also supplies fuel pump J15 , which is excited by a control signal (earth) from pin 29 of connector C of control unit M10 . This supplies power - via fuse F3 of junction unit B1 to fuel pump N40 , which is earthed through inertia switch I50 , which cuts off the circuit in the case of impact to prevent the danger of fuel flowing out. Pins 3, 7 and 8 of connector A of control unit M10 are earthed and used as references: the first two for the ignition and the third for the injectors. Pin 8 of connector F is also earthed. The engine control unit M10 receives signals from the various sensors in order to monitor all engine service conditions. Rpm sensor K46 supplies information on engine speed via a frequency signal sent to pins 37 and 38 of connector E of control unit M10 . Timing sensor K47 receives a reference earth from pin 39 of connector E of control unit M10 and sends back a frequency signal corresponding to the timing to pin 40 of the same connector. Engine temperature sender unit K36 receives a reference earth from pin 28 of connector E of control unit M10 and supplies a signal proportional to the coolant temperature to pin 29 of control unit connector E. The same sender unit also supplies information to the temperature gauge and warning light ( 3309717SeeE4010INSTRUMENT PANEL ). Hot lambda probe K40 provides control unit M10 with information on the correct composition of the air-fuel mixture. The signal is sent to pin 23 of connector C of the control unit, while pin 31 provides a reference earth signal. Probe K40 is heated by a resistor in order to ensure it works efficiently even when cold; the resistor is supplied by the relay J10 and receives the heating signal from pin 5 of connector A of M10 . Knock sensors K50 and K51 provide information on knock status via frequency signals sent to pins 42 and 44 respectively of control unit connector E. An earth signal is sent from pins 41 and 43 of connector E of M10 respectively. Air flow meter K41 (supplied from relay J10 ) receives a reference voltage from pin 46 of control unit connector E and sends to pin 47 of the same connector a signal proportional to air flow. K41 also contains an air temperature sensor: the sensor reference earth is supplied by pin 48 of connector E of M10, while pin 45 of connector E receives an air temperature signal. Accelerator pedal K55 is fitted with two built-in potentiometers (a main one and a safety back-up). The first receives power and earth from pins 22 and 23 respectively of connector C of M10 and sends a corresponding signal to pin 24 of the same connector. The second receives power and earth from pins 27 and 26 respectively of connector C of M10 and sends a corresponding signal to pin 25 of connector C. Pin 14 of connector D of M10 receives a signal from brake light switch I30 , ignition-operated (INT/A) through a line protected by fuse F1 in junction unit B1 ( 3309181SeeE2021BRAKE LIGHTS ). Pin 19 of connector D of M10 receives an earth signal from clutch pedal switch I31 . Injectors N70 receive a power supply to enable opening from main relay J10 . The engine management unit sends commands to the injectors from pins 25, 13, 1, 26, 14 and 2 of the connector, for cylinders 1, 2, 3, 4, 5 and 6 respectively. Control unit M10 also controls coils A30 via control signals for the coil primary windings, while the secondary winding sends a pulse to the spark plugs: pins 20, 6, 17, 13, 19 and 5 of connector F control ignition coils 1, 2, 3, 4, 5 and 6 respectively. The primary windings of the coils A30 receive a signal to enable opening from main relay J10 . Throttle body actuator N75 is fitted with two built-in potentiometers connected in parallel: they control throttle opening via a stepper motor. The motor receives information from pins 1 and 2 of connector F of M10 . Pin 33 of connector E sends a power supply to both potentiometers, pin 32 of connector E supplies an earth signal to the potentiometers, while pins 31 and 34 of the same connector receive signals from throttle body actuator N75 . Fuel vapour recovery solenoid L10 allows fuel vapours to pass through to the engine intake where they join the mixture entering the combustion chamber. Valve L10 , supplied by main relay J10 (via fuse B40 ), is opened by the control unit when the engine is under load via a duty-cycle signal from pin 21 of connector C of M10 . The control unit M10 is connected to the ALFA ROMEO CODE control unit M20 via a specific serial line from pin 39 of connector C; in this way if the ALFA ROMEO CODE unit does not detect a correct code, it does not issue enablement and the engine is not started.( 3309948SeeE7010CODE ). The control unit is equipped with a self-test system that may be used by connecting the unit to connector R10 : this receives indirect signals from control unit M10 via a serial line from control unit M20 described above.(pin 39 of connector C). The self-diagnostic system also generates a signal - from pin 21 of connector F - to the injection failure warning light on instrument panel E50 . This signal leaves control unit M10 , while pin 15 of connector A of E50 supplies an ignition-operated power supply (INT/A) from a line protected by fuse F1 of junction unit B1 . The speedometer signal (car speed) reaches pin 13 of connector D of control unit M10 ( 3309717SeeE4010INSTRUMENT PANEL ); the signal is generated by the ABS control unit M50 . Control unit M10 sends the instrument - via pin 38 of connector C - a signal proportional to engine rpm (see 3309717SeeE4010INSTRUMENT PANEL ). Control unit M10 is connected to the air conditioning system via pins 4 and 21 of connector E. This allows engine idling speed to be adjusted to increased engine load whenever the compressor is activated, or to turn off the compressor in the case of high speeds or high engine loads ( 3309931SeeE6021COMPRESSOR ENGAGEMENT ). The control unit also controls the engine cooling system: pin 6 of connector A, 3 of connector D and 15, 17 of connector E control activation of the relevant fan ( 3309782SeeE5020ENGINE COOLING ). Control unit M10 is connected to the electronic automatic transmission (EAT) via pins 5 and 17 of connector D ( 3310059SeeE7050AUTOMATIC TRANSMISSION ). Pins 11 and 12 of connector D of control unit M10 are connected to the ABS/ASR control unit via CAN line ( 3310008SeeE7021ASR / TCS ). Pins 20, 21, 22, 23, 24 of connector D and pin 10 of connector E of control unit M10 are connected to Cruise Control; ( 3309870SeeE5060CRUISE CONTROL ). Pin 28 of connector C and pins 23 and 24 of connector E of control unit M10 are connected to the electronic throttle opening system ( 3309896SeeE5065SPORT THROTTLE RESPONSE ). Some versions are fitted with supplementary connector R51 for connection to the control unit. This is located in the engine bay. 767This connection is used solely at the Production Plant and SHOULD UNDER NO CIRCUMSTANCES be used during servicing.
